Yes, the rural areas are predominantly Republican, and the suburbs have a lot of Republicans as well, but there are also a lot of sheltered leftists there as well. The cities imo are not as liberal as the voting stats bear out (except places like LA, Portland, Seattle), but voter fraud pays much bigger dividends in a city than it does in a small rural county.

The reason why many Republicans live in the suburbs or rural areas is due to a generation of white flight out of the cities after desegregation.
